'Hear
me, Lord of Time. We are a vengeful people. Our reach is infinite and our
patience eternal. For your actions, we will have vengeance. And the vengeance
of the Chronivores is terror beyond imagining.'

Five
thousand years ago, the Priest-Kings of Atlantis attempted to enslave Kronos,
greatest of the Chronivores. They failed, with catastrophic results. Thirty
years ago, The Master sought to do the same, and barely escaped with his
life.

London, 2003: torn apart by tragedy, The Doctor and Mel have
gone their separate ways, only to find their paths crossing once more. While
The Doctor tries to stop an old friend from making a terrible mistake, Mel is
horrified to learn that her best friend has fallen under the influence of The Master.

As The Master desperately tries to defend himself against the
power of Kronos, The Doctor and Mel must overcome their differences. If they
don't, the Quantum Archangel will be triumphant. And if she is, nothing in the
Universe will ever be the same again.
